Original Press Release:
Argweld® Weld Purge Monitor
Huntingdon Fusion Techniques has launched its MkV version in the popular range of Argweld® gas measuring equipment for use in monitoring oxygen content during welding. The new model is technically more advanced than its predecessors and is the most cost-effective in the global market.
The Argweld® Weld Purge Monitor is robust but truly portable, weighing a mere 200 gm. It has the ability to measure oxygen levels accurately down to 0.1% (1000 ppm) but will indicate down to 0.01% (100 ppm).
It is supplied with its support equipment in a custom-designed protective carrying case and features temperature compensation, continuous or sample reading and a self-calibrating function.
Removal of oxygen from the region around the joint is essential if high quality welds are to be produced. Various techniques are in use for eliminating oxygen and purging using argon is one such possibility. Whichever method of oxygen removal is used however there remains a need to monitor residual gas levels accurately before and during the welding operation. Some metals are more sensitive to becoming discoloured or contaminated due to the presence of oxygen: stainless steels and nickel alloys are particularly prone to this.
